A two-day seminar on “Performance Based Design of Reinforced Concrete Buildings” has been organized by the Asian Center for Engineering Computations and Software (ACECOMS) in collaboration with Asian Institute of Technology (AIT) Consulting, from 27-28 August, at the AIT Hotel and Conference Center (Bangkok, Thailand). RIMES Scientist and Seismic Risk Evaluation and Mitigation, Dr. Teraphan Ornthammarath, has been one of the key instructors of this seminar, providing expertise on Performance Based Seismic Design (PBSD), a new design concept for structural engineers to evaluate how a building is likely to perform when an earthquake strikes.
The objective of this seminar, which welcomed over sixty participants, was to provide consolidated theoretical background and practical knowledge on the performance-based design of reinforced concrete buildings, and to demonstrate the effective usage of structural engineering software for carrying out performance based design. Performance Based Approaches (PBA) have gained considerable acceptance in the recent years for determining and designing structures for specific hazards, especially earthquakes. PBA provides a rational and systematic way for determining the performance of structures using relatively rigorous techniques and tools, including the effects of non-linearity and dynamics to achieve specific response targets.
Dr. Teraphan provided expertise on the various components and process for Performance Based Seismic Design (PBSD) and Probabilistic Seismic Hazard Assessment (PSHA) in relation to an actual project conducted for Metro Manila, an area in the Philippines with high seismic activity. Applying the PBSD concept starts by firstly performing seismic hazard assessment to understand seismic activity surrounding the building site. In that way, it is possible to determine the level of ground shaking that should be expected as a result of future earthquakes.
“PBSD allows the design of new buildings or the upgrade of existing buildings with a realistic understanding of the risk of casualties, occupancy interruption, and economic loss that may occur as a result of future earthquakes”, explains Dr. Teraphan, who adds that with this concept, building owners would know what level of safety and what level of property protection could be expected, and at what cost are acceptable.
